I keep quite a bit on my DVR (movies for the kid, etc) so I often don't have much capacity left. Last night when I went to bed, my capacity was at 9% for HD programming. When I got home from work today it had jumped up to 36%. I reviewed the recordings and it doesn't appear as though anything was deleted. I assume they can't increase storage capacity without installing a new HD. Does anyone know why this might have happened?
